Alcohol and other drug use among older adults is an area of significant research interest, given the potential impact of substance use on health and overall well being in this growing population. Between 2010 and 2050, the number of adults aged 65 and over is expected to increase from 40 to 88.5 million (Vincent & Velkoff, 2010). Among older adult populations worldwide, alcohol is the most commonly used substance (Morin et al., 2013). Current recommendations from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) state that adults over 65 should consume no more than three drinks on any 1 day and no more than seven drinks per week (National Institute on Alcohol Abuse and Alcoholism, 2005). Approximately one-third of older men and one-tenth of older women in the United States drink above the recommend NIAAA guidelines, with a population average of 10–13 percent overall (Blazer & Wu, 2009; Sacco, Bucholz, & Spitznagel, 2009). Based on analysis of trends in substance use, future older adult cohorts will likely have higher alcohol consumption than current cohorts, as well as more experience using other drugs (Blow & Barry, 2012). Recent analysis of data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) found a substantial increase in high-risk drinking among older adults, with rates more than doubling from 2001–2002 to 2012–2013 (Grant et al., 2017). The impact of high risk drinking, and the recent increase in opioid overdoses affecting individuals across the life span, contributes to the urgency of conducting clinical and psychosocial research to understand factors associated with drinking patterns, risk factors for alcohol-related problems, other drug use, and health effects among older adults.
